Application January 12, 1948, Serial No. 1,862

The invention relates to jar vises and more particularly to vises or holders for glass jars used in preserving fruits or vegetables.

One of the objects of the invention is to provide a jar vise having angled jaws so that either round or square jars may be gripped with equal facility.

A further object of the invention is to provide a jar vise in which both jaws of the device are adjustable thus increasing the range of jar sizes that may be handled by the vise and also permitting an adjustment of the gripping tension where the jawsare provided with yieldable jar engaging faces.

The invention further consists in the several features hereinafter described and more particularly defined by claims at the conclusion hereof.

In the drawings:

Fig. 1 is a plan view of a jar vise embodying the invention;

Fig. 2 is a side elevation view of the jar vise;

Fig. 3 is a vertical sectional view taken on the line 33 of Fig. 1, parts being broken away;

Fig. 4 is a rear end elevation view of the vise;

Fig. 5 is a front end elevation view of the vise.

The vise comprises a base member 6, individually adjustable jaw members I and 8 mounted on said base member and cooperating therewith to clamp a jar J in fixed position thereon, and means for moving one of said jaw members toward the other to clamp the jar between said members.

The base member 6, which may be a one piece metal casting or formed of several sections welded or braised together, has a channel base section 9 whose legs are adapted to rest upon a suitable support I to which said member is clamped by a manually operable headed clamping screw H having adjustable threaded connection at I2 with a depending angled front plate I3 of said base member. The sides of the member 6 are provided with longitudinally extending jaw guide grooves I4, the plate I3 with an aperture I and the top with spaced centrally located slots I6 and H. A guide and spring seat bracket I8 is secured to the bottom of the top portion of the base member 6.

The jaw I is the relatively fixed jaw and is formed to provide a base portion I9 resting on the top of the base member 6 and provided with depending angled portions 29 slidably engageable with the grooves I4 and having an apertured boss 2 I adapted to receive a carriage bolt 22 whose squared shank portion 23 is slidably mounted in the slot I6 and whose threaded shank receives a clamping wing nut 24 whereby the jaw I may be fixedly clamped to the base member 6 in different 2 Claims.

' :25 each of which are faced with a relatively thick vertically ribbed facing 26 of rubber or other suitable yieldable material.

The jaw 8 is the movable jaw and has a base portion 21 resting on the top of the base member 6 and provided with depending angled portions 28 slidably engageable with the grooves I4 and having a depending apertured flange portion 29 working in the slot I! and having a nut 30 braised or welded thereto. The base portion 21 is provided with angled jaw portions 3I each of which are faced with a relatively thick vertically ribbed facing 32 of rubber or other suitable yieldable material.

The top of the base member 6 carries a pad 33 of rubber or other suitable yieldable material.

For moving the jaw 8 relatively to the base 6 and the jaw I, an operating rod 34 is slidably guided in the aperture I5 and an aperture 35 in the bracket I8 and has a threaded end 36 adjustably mounted in the nut 36. The rod 34 with the jaw 8 are moved to a release position by a spring 31 surrounding rod 34 and interposed between the bracket I8 and a washer 38 abutting the nut 30. The rod 34 with the jaw 8 is moved to a jar clamping position by cam means associated with an operating handle 39 and comprising a pair of metal disks 4!] fixed to said handle and eccentrically pivotally connected to the extended end H of the rod 34 by a pin 42, said disks adapted to engage the front end of the base member 6 and draw said rod forwardly as the handle is swung from the dotted line position shown in Fig. 2 to the full line position shown therein. The handle 39 also permits the rod 34 to be turned in the nut 30 so as to adjust the position of the jaw 8 on the base 6 prior to moving this jaw to its jar clamping position.

In using this vise, a jar 9 is placed in upright position on the pad '33, and then both jaws I and 8 :are adjusted lengthwise of the base *6, the jaw I by the shifting and tightening of the bolt 22 by the nut 24 and the jaw :8 by the turning of the rod 34 in the nut 30, to bring the jar 9 approximately centrally of the pad when the jaw 8 is moved by the downward swinging movement of the handle 39 toward the fixed jaw I. This adjustment having been made, the requisite tensioning pressure of the jaws on the jar is obtained by moving the jaw -8 to a release position and turning the rod 34 one and a, half to two turns so as to further advance the jaw 8 relative to the base 6, and then on the movement of the J'aw 8 to its clamped position by the downward swingin movement of the handle 39 the jar will be tightly clamped to the base 6 between the cushioning faces 26 and 32 of the jaws 1 and 8 and without danger of breakage, so that the cover for the jar may be readily turned by a suitable tool to either an open or closed position. Since the faces of each jaw make an angle of ninety degrees with respect to each other, jars of square or rectangular body sections may be as readily clamped between the jaws as the more usual cylindrical body jars.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claims.

What I claim as my invention is:

1. In a jar vise, the combination of a base member, of a pair of jaws mounted on said base member, means for securing one of said jaws in a fixed position on said base member, the other of said jaws being slidably mounted and guided on said base member and having a, threaded portion, an operating rod slidably mounted on said base member and having a threaded end adjustably mounted in said threaded portion, manually operable cam means associated with said rod and engageable with said base member for moving said slidable jaw to a jar clamping position, and spring means for returning said slidable jaw to a release position.

2. In a jar vise, the combination of a base member, of a pair of jaws slidably mounted on said base member and provided with jar engaging facings of yieldable material, means for adjustably clamping one of said jaws in a fixed position on said base member, means for moving the other of said jaws toward the first named jaw to a jar clamping position including a reciprocatory rod, and a direct threaded connection between said rod and the jaw moved thereby for adjusting the tensioning engagement of said facings with the jar.
